Description
Technical field
The present invention relates to measuring equipment field, more particularly to a kind of gas-metering device.
Background technology
Drainage is a kind of conventional method for collecting gas.
Specific implementation method is：As shown in figure 4, being placed upside down in after gas bottle is filled into saturated liquid in tank, bottleneck is less than
Liquid level.Then gas discharge outlet is positioned over below bottleneck.Until all saturated liquid discharges in bottle, then full gas is collected.
Saturated liquid is that the gas not with that should collect reacts, while the gas that should be collected will not largely be dissolved in liquid therein
Body.
Its advantage is：Gas than being obtained to upper (lower) air-discharging method is pure, does not have the remaining gas of doping.
Its shortcoming is：Contain substantial amounts of water droplet in the gas of collection, generally require desiccant dryness.
Existing resolver measures gas volume caused by thing to be desorbed using drainage, and passes through naked eyes measurement data
Change.
Because above-mentioned gas metering process is that a high-frequency is persistently measured for a long time, experimenter is needed every certain
Time changes collection vessel and collects once result, therefore big using human metering workload, wastes time and energy, and the essence of gathered data
Exactness is low.
Based on this, the invention provides a kind of gas-metering device to solve above-mentioned technical problem.

For convenience of description, the air inlet pipe connected with first collection vessel is named as air inlet pipe one, the row
Tracheae is named as blast pipe one, and the air inlet pipe connected with second collection vessel is named as air inlet pipe two, the exhaust
Pipe is named as blast pipe two.Liquid surface has surface tension, all to act on liquid surface, the power for reducing liquid surface area,
Referred to as surface tension of liquid.Its Producing reason is that liquid has a thin layer with the surface that gas contacts, and is called superficial layer, table
Molecular proportion liquid internal in surface layer is sparse, and intermolecular distance is larger than liquid internal, intermolecular interaction performance
For gravitation.Such as the application, when saturated liquid is full of in first collection vessel and the sufficiently fine catheter, it is described enter
The valve of tracheae one and the blast pipe one is turned off, therefore inside is the full pendular ring border full of saturated liquid, if saturation
Catheter flows down described in liquid runs down, and inside can produce negative pressure of vacuum, prevent it from flowing down.Meanwhile the catheter is sufficiently fine
Tubule, the liquid level of tubule end is spherical in shape, and the radius of saturated liquid surface tension and tubule is in inverse ratio, and tubule radius is smaller,
Saturated liquid surface tension is bigger, and tubule is sufficiently fine, when the pressure that the surface tension and atmospheric pressure of the liquid level provide is more than
During saturated liquid gravity, i.e. atmospheric pressure+surface tension>Saturated liquid gravity, saturated liquid will not flow out along tubule.Cause
And the saturated liquid of herein described first collection vessel will not be automatically flowed into second collection vessel.
When will collect the gas that the specimen reaction device specimen reaction discharges, the specimen reaction device is passed through

After first collection vessel collects full gas, second collection vessel is placed in described first by rotating
The top of collection vessel, the valve of the air inlet pipe two is opened, close the valve of the air inlet pipe one, open the blast pipe one
Valve, release the gas of collection, keep the air pressure balance with atmospheric pressure, close the valve of the blast pipe two.Constantly repeat
Above-mentioned steps, until having collected the gas.Radio frequency capacitance apparatus being capable of analytical equipment immersed in liquid level part and exposed to gas
The capacitance of middle part, judges liquid level position, and the gas volume of collection is calculated eventually through the analysis of external analytical equipment.
Or the valve of the blast pipe of first collection vessel is opened, make second collection vessel by power set
Interior saturated liquid enters in first collection vessel, then constantly repeats above step until having collected the gas.
Radio frequency capacitance apparatus can analytical equipment immersed in liquid level part and in gas part capacitance, judge liquid level position,
The gas volume of collection is calculated eventually through the analysis of external analytical equipment.
It is anti-by first collection vessel and the continual collection sample of second collection vessel by above-mentioned setting
Gas caused by answering, the gas volume of collection is calculated by radio frequency electrical appearance device analysis.Collection vessel need not be constantly changed,
Avoid the loss of gas, it is not required that manually calculate gas volume, workload is small, saves the time, improves efficiency, and improve
Accuracy.
